Part A: Create a fifth-degree polynomial with four terms in standard form. How do you know it is in standard form? Part B: Explain the closure property as it relates to subtraction of polynomials. Give an example.

Me solve this problem, and someone clearly explain to me how to solve it.1.) use the value of the discriminant to determine if the given trinomials has 2 real solutions, 1 real solution, or no real solutions.a.  x2  − 4x  − 7 = 0b. 4r2  + 11r  − 3 = 0c. 3m2  + 7 = 0d.  t2  + 2t  + 1 = 0

Aphrase is shown read the phrase and give me the answer

What is the simplified form of square root of 400 to the 100th power ?
